The left gauge of a stock:

14 Be convinced that the return valve-1 is inserted into a levelling hose of a tank.

15 Insert the gauge and hold it approximately on 5 sm above a tank. Fix the gauge in a groove on a tank.

16 Level the gauge, having turned it. Thus the pad in the top part of the gauge should enter into a tank groove.
17 Put on and tighten накидную a nut. Thus the lock should enter a pad into a corresponding groove on a tank, distinctly having fixed.
18 Attach fuel hoses according to marks and fix their new collars.
19 Join штекерные connections and fix them.
20 Establish a cover and fix it, watching thus correct position of consolidation.
21 Insert into a cover a rubber epiploon. Will put back изоляционный a floor-mat.
22 Establish into place a back seat, address to Section Removal and installation of a back seat.
23 Attach a negative cable (-) the storage battery at the switched off ignition. Establish hours.
